ELLSWORTF E. FLORA AND ROBERT J. ZORGE, OF CHICAGO, ILLINOIS, ASSIGNORS TO ZORGE i SAFETY RAILWAY EQUIPMENT COMPANY, ILLINOIS.

OF CHICAGO, ILLINOIS, A CORPORATION OF RAILWAY SIGNAL AND TRAIN-CONTROLLING- MOHMHSM.

To all whom it may concern.

Be it known that we, ELLswonriI E.- FLonA and Ronnnr J. Zonsn, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improve-- ment in Railway Signal and Train-Controlling Mechanism, of which the following is a specification.

This invention relates particularly to means for giving warning to an engineer, or motornian, approaching an open switch, an open draw, or other danger point with his train, or car, and to means for automatically applying the brakes if the warning is not heeded.

The primary object of the invention, is to provide improved apparatus for stopping a train, in the event that the alarm signal employed is not heeded; and a further object is to provide, in combination with such mechanism, means for giving an alarm signal prior to the operation of the automatic train-controlling mechanism, in order that the engineer, if he heeds the signal, may bring his train to a stop gradually under his full control.

The invention is illustrated in its preilerred embodiment in the accompanying drawings, in which Figure 1 represents, by a view diagrammatic in its nature, a portion of a railway track equipped wlth our improvements; Fig. 2, an end elevational view of an engine, or motorcar, equipped with the'train-carried portion of our mechanism for automatically stopping a train; Fig. 8, a-broken sectional view taken as indicated at line 3 of Fig. 4- and showing the construction at the upper portion of a standard employed for carrying'a movable stop-arm which normally occupies an inoperative position; Fi a broken section taken as indicated at line 4. of Fig. 3; Fig. 5, a broken side elevational view of the parts shown in Fig. 3; Fig. 6, a broken section taken as indicated at line 6 of Fig. 5; Fig. '2', a plan view of the parts shown in Figs. 5 and 6;Fig. 8, an enlarged broken detail View showing a construction at the central portion of the rock-shaft shown in Fig. 2:; Fig: 9,, a hrokensection taken as indicated at line 9 01 Fig. 8; Fig. 10, a

sents a railway track electrically divlded fi'o into sections A, A and A with a movable switch-point A, operated by a bar A connected with the operating lever A of the switch-point; B, torpedoplacing mechanism controlled by a circuit B having a branch circuit. B connected with the switch-point or operating means therefor, and having a branch B controlled spectively, with the track-sections A, A"; B, mechanism connected with the circuits B and B and serving automatically to control the branch circuit 13 said mechanism automatically to open the circuit B when a train approaches the switch-point in the di- I rection indicated by the arrow; G, local train-controlling mechanism located at one side of the track between the tor ode-placing mechanism B and the switc -point and equipped with a movable stop-arm O operatively connected with the switch in a manner to be presently described; and D,..traincarried 'valvcactuating mechanism mounted on the engine D and'serving to operate a relief-valve whose function matically set the brakes.

The details of construction of the torpedoplacing mechanism 13 and the means for it is to autoautomatically controlling the operation ofthe same are fully described in our application No. 879,791, filed June 19, 1907. It is suflicient to state here that when a train approaches the switch-point in the direction indicated by the arrow in Fig. 1, assuming the switchvpoint to be open and thsgbranoh circuit B broken, the branch cir it @15 will be opened, thereby opening the circuit immediately coimeoted with. the torpedo-placing mc'chanismB, whereupon the torpedo.- placing mechanism will operate to project a torpedo above the adjacent track-rail; and

theconstruction and arrangement are such that when a train passes in the opposite di, rection, the branch circuit B will not be opened, and the torpedo mechanism will not op ate.

Thus, the torpedo-placing mechanism B will not operate unless the switch-point A is open. It may be stated that under ordinary conditions of service, where careful engineers are employed, the automatic traincontrolling mechanism C would seldom be called upon to perform the duty of bringing the train automatically, to a stop, since the engineer, upon receiving the warning signal, would bring the train to a stop under control; as above set' forth. Thus, the invention'provides for the operation of trains. under the' most economical conditions, and also provides against injury to the trains which might otherwise re'sult lnvthe construction illustrated the movable stop G is positively actuated in both direc tions.- It may be stated, however, that even should the sto lowering connections between the mova le stop-arm and the switch-- lever Al'become broken, the movable stoparmwould-nevertheless automatically fall to the. operative position when the switch point was thrown open.

The stop-a1 C carries a shield 43, which serves, when said arm is in the elevated posi tion, to cover a lamp 44 surmounting the part 1; The lamp may be fitted with a red glass front, so that a danger light will show when the arm 0 is dropped to the operative position I The foregoing detailed "description has been given for clearness of understanding .only, and no undue limitation should be understood therefrom. a What we regard as new, and desire to secure by Letters Patent,-is-- Y 1 1. The combination with a railway track,

of torpedo-placing mechanism located in advance of a point to'be protected, electric controlling means therefor provided.ui.th a circuit, and local train-controlling meanslocated between the point to be protected and I .the torpedo-placing mechanism and comprising a movable stop-arm, mechanical actuating means therefor, and circuit-interruptmg means for said circuit connected withsaid mechanical actuating means. M

2. The combination with a railway track, and train-carried train-controlling mechanism, of local train-controlling mechanism comprising a standard, a movable stop-arm mounted thereon and having a shaft equipped with a sprocket-wheel, a sprocketchain connected with said wheel, an actuating-lever located at a distance from said standard, and flexible connections joining the, ends of said sprocket-chain and said actuating-lever, whereby said movable stop 'may be positively actuated in two directions.
